title: [Diagnosis of obstructive coronary artery disease using CT coronary angiography combined with CT first-pass myocardial perfusion imaging at rest].
abstract: OBJECTIVE
  To assess the feasibility and accuracy of CT coronary angiography (CTCA) combined with CT first-pass myocardial perfusion imaging (CT first-pass MPI) at rest for diagnosis of obstructive coronary artery disease (CAD).
  
  
  METHODS
  Fifty-five patients, suspected or diagnosed as CAD, were performed with CTCA and CAG within 2 weeks. CT first-pass MPI detected myocardial ischemia through analyzing the raw date of CTCA.
  
  
  RESULTS
  Comparison with the results of CAG, the sensibility, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of CT first-pass MPI at rest for detecting obstructive CAD were 84.6%, 68.8%, 86.8%, 64.7% and 80.0%, respectively; and 92.3%, 93.8%, 97.3%, 83.3%, 92.7% for CTCA combined with CT first-pass MPI, respectively.
  
  
  CONCLUSIONS
  CTCA combined with CT first-pass MPI at rest could detect obstructive CAD feasible and accurately.
